FM Global and their laboratory testing and classifications subsidiary, FM Approvals, serve as a reference standard in many designer's roof system designs.

Graham, NRCA's vice president of technical services, will provide an overview of FM Global's and FM Approval's role in the roofing industry, review recent changes to FM Global's Property Loss Prevention Data Sheets and show examples of how these changes can impact roof system designs.
